Considering the small price difference, I'd personally go with the cats. If high flow cats were a huge difference in price, then perhaps I'd consider straight pipes more seriously.

Gabe, what is this quantity of "virtually nil" in terms of hp and torque at the low end? If this amount is so small, why offer straight pipes and high flow cats? One more thing, can you ask eloy to list weights of each listed section?
